Connecting the Calibration Units to the Network Analyzer
The calibration units provide the following connectors:
 Calibration units R&S ZV-Z51/.../-Z55, R&S ZN-Z151 or R&S ZN-Z153
 A USB type B connector at the rear is used to power-supply and control the unit. A USB
cable for connection to the network analyzer is provided with the calibration unit.
 Two or four RF connectors numbered 1 to 4 are to be connected to the test ports 1 to 4 of
the analyzer. The connector type is equal for all ports. Depending on the calibration unit
model, it is either type SMA (f), N (f), 3.5 mm (f), 2.92 mm (f) or 2.4 mm (f).
 Calibration unit R&S ZN-Z51
 A USB type B connector at the rear is used to power-supply and control the unit. A USB
cable for connection to the network analyzer is provided with the calibration unit.
 Two or four RF connectors numbered 1 to 4 are to be connected to the test ports 1 to 4 of
the analyzer. Depending on the calibration unit model and the equipped adapters, the
connector types can be 3.5 mm (f or m), type N (f or m), 7/16 (f or m) or 4.3-10 (f or m).
 Calibration units R&S ZV-Z58/-Z59
 A USB type B connector at the front is used to control the unit. A USB cable for
connection to the network analyzer is provided with the calibration unit.
 The RF connectors numbered 1 to 8 / 6 are to be connected to the corresponding test
ports of the analyzer. The connector type is type N (f) or 3.5 mm (f) for all connectors.
To connect the unit...
1. Switch on and start-up your network analyzer.
2. To protect your equipment against ESD damage use the wrist strap and grounding cord supplied
with the instrument and connect yourself to the GND connector at the front panel.
3. Connect the USB type A connector of the USB cable to any of the USB type A connectors on the
front or rear panel of the analyzer. Connect the USB type B connector of the USB cable to the
USB type B connector of the calibration unit.
4. Wait until the operating system has recognized and initialized the new hardware. When the unit is
connected for the first time, this may take longer than in normal use.
The unit is ready to be used when the Channel – Calibration – Start Cal – Calibration Unit menu command
is available.
Note:
 The calibration unit is intended for direct connection to ZVA network analyzers
following the procedure described above. You can also connect the unit before
switching on the analyzer. Do not connect the unit to other USB hosts, e.g. a
PC, or insert any USB hubs between the analyzer and the unit, as this may
cause damage to the unit or the host.
 You can connect several calibration units to the different USB ports of the
analyzer. You can also connect cal units and other devices (mouse, USB
memory stick etc.) simultaneously.
 An unused calibration unit may remain connected to the USB port while the
network analyzer is performing measurements. It must be disconnected during
a firmware update.
